TortoiseSVN isn't ignoring directory present in svn:ignore

Question

I'm trying to ignore a complete directory with TortoiseSVN.

First here a glimps of the start of 'Check for modifications'.

There is only files that are in 'bin' directory and all are 'unversioned'.

But here is the catch for the properties of the directory are these :

And further more i added the bin file in the global ignore list of Tortoise SVN ...

I don't know why it's still showing while other directories like 'target' are all well taken care of...

Thanks in advance if someone has a idea.
